Description

A plug, a socket, and an endoscope Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to a plug, a socket, and an endoscope. Background Technology

[0002] An endoscope is a commonly used medical device used to directly access the body's natural cavities for examination, providing doctors with comprehensive diagnostic information. An endoscope typically includes: an insertion section for insertion into the body, a manipulator for easy operation, and a display device for visualizing the internal environment of the body's natural cavities. The insertion section and manipulator can be collectively referred to as the operating section. The operating section and the display device establish a communication connection via a pluggable connector. Through the coordination of these three parts, the endoscope enables visualization of the body's interior, exploration of lesions, and treatment.

[0003] In existing technology, plugs and sockets are generally connected by a snap-fit ​​mechanism. Unplugging requires force to overcome the snap-fit ​​force. Not only is the plug difficult to remove, but the socket is also prone to loosening after prolonged use. Furthermore, the reliability of the cable connection decreases over time, and the cable's lifespan is significantly shortened. Utility Model Content

[0004] In view of the shortcomings of the aforementioned related technologies, this application provides a plug, a socket, and an endoscope to solve the above-mentioned technical problems.

[0005] This application provides a plug, including a connector, a housing, and a driver. The connector has a snap-fit ​​portion and has a mounting end and an insertion end that are spaced apart from each other. The mounting end is used to install a cable, and the insertion end is used to insert into a socket and make an electrical connection. The housing is fitted onto the connector and slides in cooperation with it. The housing has a mounting hole corresponding to the snap-fit ​​portion. The snap-fit ​​portion extends into the mounting hole to form a first snap-fit ​​assembly. The first snap-fit ​​assembly is used to snap-fit ​​with a second snap-fit ​​assembly of the socket. The driver is connected to the mounting end and is used to drive the connector to move between a first position and a second position. When the connector moves from the first position to the second position, the snap-fit ​​connection between the first snap-fit ​​assembly and the second snap-fit ​​assembly is released.

[0006] To achieve the above and other related objectives, this application provides a socket for connecting to the aforementioned plug. The socket includes a socket housing and a socket connector. The socket housing is provided with a second snap-fit ​​component, which is used to snap-fit ​​with a first snap-fit ​​component of the plug. The socket connector is installed inside the socket housing and is used to electrically connect to the plug. When the socket connector is electrically connected to the plug, the second snap-fit ​​component of the socket snaps-fit with the first snap-fit ​​component.

[0007] To achieve the above and other related objectives, this application provides an endoscope, including an operating part and the aforementioned plug, wherein a cable connected to the operating part is electrically connected to a connector of the aforementioned plug.

[0008] The technical solution adopted in this application achieves the following beneficial effects: the connector can be inserted into the socket and electrically connected to it. The snap-fit ​​part of the connector and the mounting hole of the housing form a first snap-fit ​​assembly, which can cooperate with the second snap-fit ​​assembly of the socket to make the plug and socket snap-fit ​​connected and fixed. The driving member can drive the connector to slide relative to the housing, and during the sliding of the connector, the snap-fit ​​connection between the first snap-fit ​​assembly and the second snap-fit ​​assembly is released, making it easier for the plug to be unplugged from the socket. The unplugging method is easier and will not damage its own structure or cable structure, significantly increasing the reliability and service life of the cable connection.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] In the various embodiments of this application, "near end" and "far end" refer to the distance of each component from the user in the usage environment. The end closer to the user is designated as the "near end", and the end farther from the user is designated as the "far end".

[0026] An endoscope is a commonly used medical device used to directly access the body's natural cavities for examination, providing doctors with comprehensive diagnostic information. An endoscope typically includes: an insertion section for insertion into the body, a manipulator for easy operation, and a display device for visualizing the internal environment of the body's natural cavities. The insertion section and manipulator can be collectively referred to as the operating section. The operating section and the display device establish a communication connection via a pluggable connector. Through the coordination of these three parts, the endoscope enables visualization of the body's interior, exploration of lesions, and treatment.

[0027] In existing technology, plugs and sockets are generally connected by a snap-fit ​​mechanism. Unplugging requires force to overcome the snap-fit ​​force. Not only is the plug difficult to remove, but the socket is also prone to loosening after prolonged use. Furthermore, the reliability of the cable connection decreases significantly over time, and the cable's lifespan is drastically shortened.

[0028] To address the aforementioned technical problems, this application provides a plug 100. Referring to Figure 1, the plug 100 may include a connector 110, a housing 120, and a drive member 130. The housing 120 is sleeved on the connector 110 and slides in cooperation with the connector 110, while the drive member 130 is connected to the connector 110.

[0029] Referring to Figures 1 and 2, connector 110 has a mounting end 110a and an insertion end 110b that are spaced apart from each other. Mounting end 110a is used to mount a cable, and insertion end 110b is used to insert into and electrically connect to socket 200. Exemplarily, connector 110 includes, but is not limited to, one or more pins. One end of the pin is used to mount a cable, and signals or current are transmitted to the pin through the cable. The end of the pin furthest from mounting end 110a extends to insertion end 110b, which is used to insert into socket 200. The pins of connector 110 can be electrically connected to the pins of socket 200, thereby enabling signal transmission or power supply.

[0030] The cable can be an optical fiber or a wire or a combination thereof. For example, the cable can be a combination of a wire and an optical fiber. The connector 110 is provided with pins and optical fiber pins. This embodiment is not limited.

[0031] Please refer to Figure 1. The connector 110 may be provided with a snap-fit ​​portion 111. The protruding snap-fit ​​portion 111 facilitates the snap-fit ​​portion 111 to engage with other components. More specifically, the snap-fit ​​portion 111 has a bevel, the thickness of which gradually increases from the insertion end 110b to the mounting end 110a. This bevel provides a guiding function, directing other components to fit together, making it easier to accommodate minor deformations during assembly, reducing assembly resistance, and making the assembly process smoother.

[0032] Please refer to Figures 2 and 3 together. The housing 120 has a mounting hole 121 corresponding to the fastening part 111. For example, the diameter and shape of the mounting hole 121 can be corresponding to the fastening part 111. The fastening part 111 extends into the mounting hole 121 to form a first snap-fit ​​assembly 140. In other words, the mounting hole 121 and the fastening part 111 combine to form the first snap-fit ​​assembly 140. The first snap-fit ​​assembly 140 is used to snap-fit ​​with the second snap-fit ​​assembly 210 of the socket 200. The first snap-fit ​​assembly 140 can cooperate with the second snap-fit ​​assembly 210 of the socket 200 to snap-fit ​​and fix the plug 100 and the socket 200.

[0033] Referring to Figure 4, the mounting hole 121 has a first region 121a and a second region 121b that are interconnected. For example, the first region 121a is located on the side of the second region 121b that is closer to the insertion end 110b. This embodiment does not limit the volume ratio and shape of the first region 121a and the second region 121b.

[0034] Referring to Figures 2 and 4, the drive member 130 connects to the mounting end 110a of the connector 110. The drive member 130 drives the connector 110 to move between a first position and a second position. The first and second positions are sequentially distributed along the insertion direction of the plug 100 (as shown by L1 in Figure 2). Relative to the housing 120, the drive member 130 can drive the connector 110 to move along either the insertion or removal direction of the plug 100. The insertion and removal directions are opposite. When the connector 110 moves from the first position to the second position, the latching connection between the first latching assembly 140 and the second latching assembly 210 is released. The driving component 130 can drive the plug 110 to slide relative to the housing 120, and release the snap-fit ​​connection between the first snap-fit ​​component 140 and the second snap-fit ​​component 210 during the sliding process of the plug 110, so that the plug 100 can be pulled out of the socket 200 in a more convenient way without damaging its own structure and cable, and significantly increasing the reliability and service life of the cable connection.

[0035] Understandably, the connector 110 and the drive member 130 have a certain limiting effect on the housing 120. For example, the connector 110 and the drive member 130 combine to form a certain limiting space, which is used to allow at least a portion of the housing 120 to slide relative to each other. This arrangement can prevent the housing 120 from sliding excessively and causing the plug 100 to disintegrate. Thus, this arrangement can limit the relative sliding of the connector 110 and the housing 120 in a specified path, and the first position and the second position are located in this path.

[0036] In this embodiment, referring to Figure 5, the connector 110 may include a base shell 112, a connector 113, and a tail tube 114. The connector 113 is provided with one or more pins, and a fastening part 111 is provided on the base shell 112. The tail tube 114 has a first through hole 1141 for the cable to pass through, allowing the cable to pass smoothly through the tail tube 114. One end of the connector 113 is inserted into the base shell 112, and the other end abuts against the tail tube 114 and is electrically connected to the cable inserted into the first through hole 1141, so that the cable inserted into the first through hole 1141 can be electrically connected to the pins, ensuring smooth current transmission in the plug 100. The drive member 130 is connected to the base shell 112 and sleeved on the tail tube 114. This arrangement not only ensures the stability of the tail tube 114 but also allows the drive member 130 to effectively constrain and fix the tail tube 114, so that it can fix the cable.

[0037] More specifically, referring to Figure 6, the base shell 112 has a second through hole 1121. In other words, the base shell 112 forms a mounting cavity 1122, the connecting seat 113 is installed in the mounting cavity 1122, and the second through hole 1121 penetrates the cavity wall forming the mounting cavity 1122. The fastening part 111 may include a fastening block 111a and an elastic arm 111b, the fastening block 111a cooperating with the mounting hole 121. The end of the fastening block 111a away from the elastic arm 111b extends into the mounting hole 121 of the outer shell 120. This arrangement makes the connection between the base shell 112 and the outer shell 120 more secure, and also facilitates disassembly and maintenance. The fastening block 111a is located in the second through hole 1121, one end of the elastic arm 111b is connected to the fastening block 111a, and the other end is connected to the hole wall of the second through hole 1121. The elastic arm 111b has a certain elasticity. The deformable elastic arm 111b can change the positional relationship between the fastening block 111a and the connecting seat 113, thereby changing the connection relationship between the fastening part 111 and the second snap-fit ​​component 210 of the socket 200, and thus unlocking or limiting the first snap-fit ​​component 140 and the second snap-fit ​​component 210.

[0038] In one embodiment, referring to Figure 6, the elastic arm 111b may include a first connecting segment 1111, a second connecting segment 1112, and an intermediate segment 1113, with the intermediate segment 1113 connecting between the first connecting segment 1111 and the second connecting segment 1112. The end of the first connecting segment 1111 furthest from the intermediate segment 1113 is connected to the fastening block 111a, and the end of the second connecting segment 1112 furthest from the intermediate segment 1113 is connected to the wall of the second through hole 1121. The cross-sectional area of ​​the intermediate segment 1113 is smaller than that of the first connecting segment 1111 and the second connecting segment 1112. Under the same force, the deformation of the smaller intermediate segment 1113 is greater than that of the first connecting segment 1111 and the second connecting segment 1112, further improving the elastic performance of the elastic arm 111b, thereby increasing the displacement of the fastening block 111a and ensuring the normal operation of the connector 110.

[0039] As shown in Figure 2, the number of second through holes 1121 can be multiple, such as 2, 3, etc., and this embodiment is not limited. The multiple second through holes 1121 are spaced apart from each other. For example, multiple second through holes 1121 are all formed in the outer shell 120, and the multiple second through holes 1121 are distributed circumferentially along the outer shell 120. As shown in Figure 6, the number of fastening parts 111 can be multiple, such as 2, 3, etc., and this embodiment is not limited. The multiple second through holes 1121 and the multiple fastening parts 111 correspond one-to-one. The mutually cooperating second through holes 1121 and fastening parts 111 can improve the connection effect between the first and second snap-fit ​​components, avoid stress concentration on a single fastening part 111, and improve the safety of the plug 100.

[0040] Please refer back to Figure 2. During the installation or removal of the plug 100, the snap-fit ​​portion 111 will deform. The deformed snap-fit ​​portion 111 may detach from the housing 120, causing the plug 100 to disintegrate. Preferably, in this embodiment, the distance between the housing 120 and the connector 113 is less than the thickness of the snap-fit ​​portion 111. The thickness of the snap-fit ​​portion 111 can be understood as the dimension of the snap-fit ​​portion 111 in the radial direction along the base shell 112. In other words, the snap-fit ​​portion 111 deforms under drive, but it cannot be completely contained within the gap between the housing 120 and the connector 113. Therefore, the connector 113 will obstruct the snap-fit ​​portion 111, preventing the deformed snap-fit ​​portion 111 from detaching from the housing 120 and improving the structural stability of the plug 100.

[0041] Understandably, during the assembly of the plug 100, the connector 113 may obstruct the latching part 111, preventing the base shell 112 from entering the outer shell 120. In this embodiment, the installer can first assemble the base shell 112 into the outer shell 120. At this time, the connector 113 is not connected to the base shell 112, allowing the installer to easily install the base shell 112 into the outer shell 120 and extend the latching part 111 out of the mounting hole 121. The latching part 111 will not affect the subsequent installation of the connector 113. Furthermore, the installer sequentially inserts the connector 113 and the tail tube 114, and connects the drive unit 130 to the base shell 112 to complete the assembly of the plug 100.

[0042] In one embodiment, referring to FIG2, the fastening portion 111 extends out of the mounting hole 121 and outward toward the outer casing 120. In other words, the fastening portion 111 can be inserted into one side of the mounting hole 121 and extended outward from the other side, thus protruding from the outer casing 120. As shown in FIG7, the fastening portion 111 is used to be embedded in the limiting hole 211 of the second snap-fit ​​assembly 210, so that the first snap-fit ​​assembly 140 and the second snap-fit ​​assembly 210 are snapped together. The second snap-fit ​​assembly 210 can be a slot or hole, etc. When the plug 100 is inserted into the socket 200, the fastening portion 111 protruding from the outer casing 120 can be snapped onto the second snap-fit ​​assembly 210 and mutually limited, so that the plug 100 and the socket 200 are snapped together and fixed.

[0043] When the connector 110 moves from the first position to the second position, the latching part 111 is retracted into the mounting hole 121 of the housing 120, releasing the latching connection between the first latching assembly 140 and the second latching assembly 210. For example, the latching part 111 abuts against the inner wall of the housing 120. During the movement of the connector 110 from the first position to the second position, the housing 120 forces the latching part 111 to deform. The deformed latching part 111 is retracted into the mounting hole 121, thereby releasing the limiting engagement between the latching part 111 and the second latching assembly 210, and releasing the latching connection between the first latching assembly 140 and the second latching assembly 210 during the sliding of the connector 110. In subsequent processes, the installer can hold the connector 110 and the housing 120 and then pull them both out of the socket 200.

[0044] In addition, in some other cases, the installer can directly pull out the outer casing 120. During this process, the outer casing 120 can also force the fastening part 111 to deform. The deformed fastening part 111 is then housed in the mounting hole 121, thereby releasing the limiting fit between the fastening part 111 and the second snap-fit ​​assembly 210.

[0045] In another embodiment, referring to Figures 4 and 8, the second snap-fit ​​assembly 210 protrudes from the inner wall of the socket housing 230 of the socket 200. As shown in Figure 9, the snap-fit ​​portion 111 extends into the first region 121a of the mounting hole 121, thereby achieving a limiting connection between the snap-fit ​​portion 111 and the housing 120. The second region 121b of the mounting hole 121 is used to receive and limit the second snap-fit ​​assembly 210. When the plug 100 is snapped into the socket 200 and the plug 110 is in the first position, the second snap-fit ​​assembly 210 engages with the mounting hole 121 to achieve a snap-fit ​​connection between the first snap-fit ​​assembly 140 and the second snap-fit ​​assembly 210, so that the plug 100 and the socket 200 are snapped together and fixed.

[0046] Subsequently, when the connector 110 moves from the first position to the second position, the latching part 111 moves from the first region 121a to the second region 121b and pushes the second latching component 210 of the socket 200 away from the mounting hole 121, releasing the latching connection between the first latching component 140 and the second latching component 210. This releases the latching connection between the first latching component 140 and the second latching component 210, thereby unlocking the first latching component 140 and the second latching component 210. In subsequent processes, the installer can hold the connector 110 and the outer casing 120 and pull them both out of the socket 200 together. During the installation and disassembly of the plug 100, the latching part 111 of the connector 110 does not directly deform, reducing the fatigue of the latching part 111 and thus improving the service life of the plug 100.

[0047] In another embodiment, referring again to FIG6, the latching part 111 has a clearance groove 1114, the opening of which faces the insertion direction of the plug 100. The second latching assembly 210 may include a driven part 212 and a limiting block 213. The clearance groove 1114 is used to accommodate the limiting block 213 of the second latching assembly 210, and the latching part 111 is used to drive the driven part 212 of the second latching assembly 210. In other words, as shown in FIG10, in the second latching assembly 210, the driven part 212 and the limiting block 213 are connected to each other. As shown in FIG11, the clearance groove 1114 is correspondingly provided with the limiting block 213 of the second latching assembly 210, and the latching part 111 is correspondingly provided with the driven part 212 of the second latching assembly 210. When the plug 100 is snapped into the socket 200 and the connector 110 is in the first position, the limiting block 213 engages with the mounting hole 121 to achieve a snap-fit ​​connection between the first snap-fit ​​component 140 and the second snap-fit ​​component 210, so that the plug 100 and the socket 200 are snapped together and fixed.

[0048] Subsequently, when the connector 110 moves from the first position to the second position, the latching part 111 pushes away from the driven part 212 to the outside of the mounting hole 121. Simultaneously, the driven part 212 drives the limiting block 213 to move to the outside of the mounting hole 121, thereby releasing the latching connection between the first latching assembly 140 and the second latching assembly 210. This releases the latching connection between the first latching assembly 140 and the second latching assembly 210, thus unlocking the first latching assembly 140 and the second latching assembly 210. In subsequent processes, the installer can hold the connector 110 and the outer casing 120 and pull them both out of the socket 200. The latching part 111 indirectly drives the limiting block 213 used for limiting. This design improves the driving effect of the latching part 111 and reduces wear on the limiting block 213 of the socket 200, ensuring the reliability of the limiting block 213.

[0049] In this embodiment, please refer back to Figure 5. The tail tube 114 may include a tightening portion 1142, which abuts against the drive member 130. When the drive member 130 is connected to the connecting seat 113, the drive member 130 can synchronously drive the tightening portion 1142. The tightening portion 1142 is used to receive the drive from the drive member 130 and tighten in the radial direction to clamp the cable inserted into the first through hole 1141. The tightening portion 1142 can receive the driving action from the drive member 130 and can perform an effective tightening action in the radial direction. The purpose of this tightening action is to firmly clamp and fix the cable inserted into the first through hole 1141, ensuring that the cable will not easily loosen or fall off during use, thereby improving the overall stability and reliability.

[0050] In this embodiment, please continue referring to Figure 5. The tail tube 114 is provided with a first positioning block 1143. The extension direction of the first positioning block 1143 is parallel to the axial direction of the tail tube 114, ensuring precise alignment during installation. The base shell 112 has a first positioning groove 1123, and the connecting seat 113 has a second positioning groove 1131. The first positioning block 1143, the first positioning groove 1123, and the second positioning groove 1131 cooperate with each other. The first positioning block 1143 is inserted into the first positioning groove 1123 and the second positioning groove 1131 to form a stable mating relationship with the first positioning block 1143 and the first positioning groove 1123. When the first positioning block 1143 is inserted into the first positioning groove 1123 and the second positioning groove 1131, the overall stability of the connector 110 is significantly improved, ensuring the reliability and durability of the connector 110 in practical applications.

[0051] Please refer to Figures 3 and 4. The outer casing 120 is provided with a third positioning groove 122 and a third positioning block 123. The third positioning groove 122 has a certain guiding function. The base casing 112 is provided with a second positioning block 1124. The extension direction of the second positioning block 1124 is parallel to the axial direction of the base casing 112. The second positioning block 1124 is correspondingly set with the third positioning groove 122. The second positioning block 1124 is inserted into the third positioning groove 122. This arrangement can complete the assembly and positioning between the outer casing 120 and the base casing 112. The extension direction of the second positioning block 1124 is consistent with the axial direction of the base casing 112, ensuring that the plug 100 is accurately inserted into the socket 200, and that the plug 100 and the socket 200 can be stably electrically connected.

[0052] The third positioning block 123 is inserted into the fourth positioning slot 220 of the socket 200. The third positioning block 123 cooperates with the fourth positioning slot 220 on the socket 200.
